Economists for Free Trade (EfFT) are back, offering the Introduction to an unpublished – and hence unknown – report that claims £135 billion benefits from Brexit. It not only repeats the previous claim that GDP will increase by 4% if the UK adopts free trade, which I characterised as ‘doubly misleading’ in April, but it adds in an extra 2% from ‘improved regulation’, 0.6% from our net budget contribution to the EU and 0.2% from removing the ‘subsidy to unskilled immigration’. It also promises faster growth as well.

I’ll come back to free trade, but, first, what regulations will be improved? We are not told. Similarly, what subsidy to immigration? Who knows? The budget contribution to the EU may be saved, but we will need to spend much of it on providing replacements for various EU regulatory bodies such as the European Medicines Agency, on negotiating new deals on things like airlines or nuclear isotopes, supporting farmers (which EfFT apparently accepts), on customs formalities on trade with the EU, on managing alleged unfair trade and on trade disputes, etc. Until we see the details, you have to doubt these numbers.
